Both the Jews and the Christians now celebrate Pentecost.  Along with the Feast of the Passover and the Feast of Tabernacles, Pentecost was one of the major feasts of the Jews.  During these three great Jewish festivals, every male Jew living within twenty miles of Jerusalem was legally bound to go to Jerusalem to participate in the feast.  The word Pentecost is Greek for pentecostes which means “fiftieth.” The feast received this name because it was celebrated fifty days after the Feast of the Passover.  Another name for the Jewish Pentecost is Shebuot or “The Feast of Weeks“ (the “week” of seven Sabbaths between Passover and Pentecost).  It was originally a day of thanksgiving for the completion of the harvest.  During Passover, the first omer (a Hebrew measure of about a bushel), of barley was offered to God.  At Pentecost, two loaves of bread were offered in gratitude for the harvest.  Later, the Jews added to the Feast of Pentecost the element of Yahweh’s Covenant with Noah, which took place fifty days after the great deluge.  Still later, they made this feast an occasion to thank God for His Sinaitic Covenant with Moses, which occurred fifty days after the beginning of the Exodus from Egypt.
